DISTRIBUTED FEEDBACK LASER DIODE AND MANUFACTURING METHOD THEREOF |
| 摘要 |
Provided is a distributed feedback-laser diode (DFB-LD) and manufacturing method thereof. The DFB-LD includes a substrate; a lower clad layer having a grating on the substrate; an active waveguide extended in a first direction on the lower clad layer; an upper clad layer on the active waveguide; a signal pad on the upper clad layer; and at least one ground pad spaced apart from the active waveguide, the upper clad layer, and the signal pad in a second direction crossing the first direction, the at least one ground pad being coupled to the lower clad layer. |
